Which is not the characteristic of hydrophobic sols? a. They are highly susceptible to coagulation by addition of electrolytes. b. They have nearly the same surface tension and viscosity as that of dispersion medium. c. Their stability is due to both electric charge and salvation of the particles. d. Sol particles can be seen under ultramicroscope.
